Methods Immunohistochemistry was employed to detect the expression of RASSF1A gene in 39 cases of human gastric cancer tissues and 18 cases of normal human gastric tissues, and RT-PCR was used to examine the expression of RASSF1A mRNA in 4 gastric cancer cell lines, normal gastric cell lines GES-1 and positive control Hefts cells. Correlations between expression of RASSF1A gene and clinicopathological characteristics of gastric cancer were also analyzed.

应用免疫组化法分别检测39例胃癌组织标本和18例正常对照胃组织标本RASSF1A蛋白表达；RT-PCR法检测4株胃癌细胞株、正常胃黏膜细胞株CES-1以及阳性对照Hela细胞中RASSF1A mRNA的表达；结合病理学特征进行分析。

Neurilemmoma of sinus maxillaries commonly arise as solitary lesion with intact capsule,and is easily misdiagnosed due to its weak specificity of clinical features. Final diagnosis depends on pathology.

上颌窦神经鞘瘤多为单发，一般包膜完整，易于完整切除，但由于症状、体征、影像学表现缺乏特异性，应注意与其他上颌窦疾病相鉴别，确诊靠病理学检查。
